Rotary Drilling Rigs - V Version
V type mast link frame system has large backstay cylinders. They feature excellent stiffness of kinematic system which is advantageous when drilling in rock or constructing secant pile walls. Mast is lowered forward for transportation of the rig.
Summary of Main Components:Mast
- Torsion resistant box
- Capacity for transferring maximum torque over full length of mast
Crowd System
For vertical pulling or pushing of rotary drive and drilling tool with:
For vertical pulling or pushing of rotary drive and drilling tool with:
- Crowd cylinder with additional fast crowd speed
- Crowd winch with dual action hoist/pull down winch and additional fast crowd speed), wear-reducing permanent tensioning of crowd rope with rope tensioning cylinder.
Rotary Drive
- In three variants: gear box with 1 gear for constant drive, gearbox with 2 gears and gearbox with 3 gears (3rd used for spin off)
- Interchangeable kelly drive adaptor for easy replacement of wear parts
- Shock absorbing elements to protect against dynamic axial loads
Engine & Hydraulics
- Robust diesel engines from trusted manufacturers with modern electronic fuel injection systems (complying with latest exhaust gas emission standards)
- High cooling capacity even in high ambient temperatures
- High hydraulic power output with maximum power efficiency due to generous design of gate valves and hose pipes.
- Most advanced hydraulic systems with integrated load sensing, LUDV systems and required volume control when using different drilling processes (e.g drilling with kelly, attachment of casing oscillators, double rotary drive systems)
- Control systems developed by BAUER are designed for use in rough site environments and conditions of extreme temperature.
Winches
- Optimum conversion of engine power into winch line pull & speed
- Wide grooved drum & rope roller guide for clean rope spooling in all layers
- Designed for heavy duty continuous operation
- Free-wheeling winch or freefall facility winch with residual line pull and slack rope automatic
